Q: Errors when opening Calendar on Maverick

I'm getting an error "The server responded with "400" to operation CalDAVMigrateToServerQueueableOperation." when opening the Calendar application. The events from the iCloud Calendar do update the Calendar events, and vice-versa, but the error must be dismissed several times.  Any ideas? 

iMac, iOS 7.0.6
